[Ur] FFI - initialization and shutdown logic for third-party modules

[foldr at tutanota.com]

Hi,

Is there any mechanism to reliably initialize a third-party library on Ur/Web 
application startup and de-initialize it (once only!) on application 
shutdown?

I probably can use [initialize] task in the beginning, but I need to ensure 
that it completes before any requests are processed by the application - can 
I rely on that? I have not found anything similar for shutdown 
de-initialization.

See [1] for a practical example (notes at the bottom of the page).
